Coal mine fires have continuously remained the primary disasters in coal mining worldwide. Cement-based inorganic foam concrete, e.g., for engineering filling and coal mine fire extinguishing, has become the first choice for responding to such fires. The objective of this study was to propose quick-solidifying foamed concrete materials based on laboratory tests, and to test the properties of these materials. The stability of a foamed slurry and solidified stone of a quick-solidifying foamed concrete were tested, along with the rheological properties, curability, shrinkage, high-temperature resistance, and cracking of the slurry during solidification. The laws and values of these characteristics were obtained. The results finally show that the quick-solidifying foamed concrete developed in this study has good performance with regard to filling and fire prevention in the large spaces of a mine.

煤矿火灾一直是全世界煤矿开采中的主要灾难。例如，用于工程填充和煤矿灭火的水泥基无机泡沫混凝土已成为应对此类火灾的首选。这项研究的目的是根据实验室测试提出快速固化的泡沫混凝土材料，并测试这些材料的性能。测试了快速固化的泡沫混凝土的泡沫浆液和固化石的稳定性，以及流变性能，可固化性，收缩性，耐高温性以及固化过程中浆液的开裂。获得了这些特性的规律和价值。
